Comment Comparatively speaking, lava moves slowly. (Score 2) 64
If I lived in an area susceptible to volcanic activity, I'd have a plan in place to bug out in the event of an event. Compared to most natural disasters lava moves slowly and for the most part, scientists are able to accurately predict eruption risk ahead of time. I wouldn't wait until told to leave.
I live in an area with a wildfire risk, and in fact last summer this area lost over 500 homes to the, "Black Forest Fire". My place was evacuated but didn't suffer any loss. Wildfires move quite a bit faster than a lava flow.
